Patented Dec. 29, 1914.

Application filed September 7, 1911. Serial No. 648,159.

To all whom it may concern;

Be it known that I, CHARLES IDE Lunacsnvros, a citizen of the UnitedStates, residing at West Nutley, in the. county of Essex and State ofNewjersey, have invented new and useful Improvements in Machines forPrinting Photographic Paper, of which the follo'wingis a specification.

The present invention relates to improvements inapparatus for printingphotographic papers and materials, and part cularly blueprint paper, andit has for its object primarily to provide a generally improved machinewhich may be operated economically. and with facility.

A subsidiary object of the invention is to provide exposing mechanismfor an apparatus of this kind which insures uniform (l1s-.

tribution of the light during the printing operation, causing allportions of the resulting print to be of the same tone or exposure, a

the exposing mechanism preferably embodying arc lamps which are mountedon ,a hinged or movable carrier whereby these lamps may be readilyshifted to operative printing position, and they may be readily movedinto an inoperative position, thereby rendering; the lamps freelyaccessible for cleaning, adjustment, and renewal of the carbons orelectrodes, and while the exposing mechanism is in inoperativeposition,the transparent surface which the sensitized web passes is freelyaccessible for cleaning purposes.

Further objects of the invention are to provide improved and efiioienttension and guiding means for insuring proper passa e of the sensitizedweb with respect to t e exposing apparatus; to provide a compeneatingand winding roller for rolling the web, which will. allow for theincreasing diameter of the roll of material and to provide means forreadily adjusting the relative movement chine.

To these and other ends, the invention consists of certain improvedcombinations and arrangements of parts, all of which will be hereinaftermore fully described, the

features of novelty being pointed out particof the web through themainvention, and adapted to carry out the objects before described Fig.2represents a front elevation partly in section, of the right hand sideofthe machine as viewed from the left in Fig. 1, part of the machinebeing broken awa Fig. 3 is a view similar to Fig. 2, showing inelevation the left hand side of the machine as viewed from the right inFig. 1, parts of the machine being broken away; Fig. 4 represents atransverse section of the machine immediately above the exposingmechanism and on the line H of Fig. 5, parts'being broken away andomitted for clearness; Fig. 5 represents an interior vertical section ofthe exposing mechanism and related devices on the line 5-5 of Fig 4 Fig.6 is a detail top planview of the automatic tension and guiding rollersfor the belts which feed the sensitized web past the exposing mechanism.

Similar parts are designated by the same reference characters in theseveral views.

The accompanying drawing shows one I embodimentof the invention, and inthis form of the invention the machine is especially adapted for use inthe blueprint paper. It will be understood,

however, that the invention is not restricted rangement of-parts, in.order that the in:

vention may be applied to the best advantage according particular case.

In the present instance, the machine comprises generally a frames 1 and2, which may be of flanged or rigid afford the necessary or desiredrigidity. The side frames are connected at the top by angle irons3 audt; atthe bottonrby angle irons 5and '6; and at the back by T- shapedcross bars 7 and 8.

Theside frames of the machine are formed with segmental or substantiallysemicircular portions 22, which receivejand support a similarly shapedglass or transparent me dium 23, the ends of the latter resting uponstrips of asbestos or similar yieldable material 24, which areinterposed between the glass and the side frames of the machine to avoidbreakage or stress upon the glass.

pair of front and rear guide rollers and 26 are mounted at oppositesides of the glass 23, which forms the wall of an exposing in order thatthe web of sensitized'papermay be evenly and properly fed around theglass. In the present instance such means comprises a shaft 128, theopposite ends of which are fixed in the side frames of the and thisshaft has two sets of guiding and tensioning rollers 29 and 30 mountedthereon. Each of these rollers is flanged,

5 for the purpose of guiding the belts and preventing lateral shiftingor interference between the belts, the rollers being staggered and theflanges of the rollers at one side of the shaft being in substantialalinement with the flanges of the rollers at the opposite side of the'shaft' Each roller is mounted in a yoke shaped frame 31,-having hubs 32which are loosely on aged on the shaft 28, and each of these 'rames hasan arm which receivesone end of a tension spring 34, one end of eachspring being attached toarela tively fixed cross bar 35. belts 27coiiperate with the set of tension rollers 29, while the remaining beltsco'ciperate with the tension rollers 80, these tension rollers havingindividual springs which op-' erate at all times to draw the respectivetension rollers downwardly and therebymaintain proper tension upon thebelts.

The driving rollers 25 and '26 are provided with stud shafts 37 and 38,which cooperate with ball bearings 39 and 40 in the side frame'2 of themachine, and these stud shafts of the two rollers have sprocket wheelst1 and 4:2 fixed thereon, these two sprocket wheels being connected byan endless chain 43 which serves to insure uniform; rotation of the twofeed rollers The said shaft 38 of the driving roller 26also has a wormwheel 4% fixed thereto,"and a worm t5 cotiperates with this worm wheelto rotate The worm45 is fixed to a shaft 46, the latter being mounted inbearings formed on a suitable bracket at, and the 4:6 is connected. by alower end of the shaft universal joint 48 to a variable speed drivingshaft t9, the latter being formed with an axially extendingkey way 50.The lower end of the shaft a9 is mounted in a suitable bearing 51, andthis hearing 51 is. acted on spring 52, this compression by acompression 0 spring being contained w thin a suitable housing 53 whichis" fixed to the frame of the machine and is provided with a set screw54, the set screw coiiperating with the spring shifting of The alternatev 'a rocking dog 70 which is In the present instance,

for varying the power or compression thereof, for a purpose thatv willbe hereinafter described. The shaft 4 9 is provided with a wheel 55, thehubs 56 of which are mounted to slide axially of the shaft 49, and thesehubs are provided with keys 56 which oper ate in the key way; of theshaft 49 and thereby form a spline connection'which insures the rotationof the wheel '55 and the shaft 49in unison, and also permits axial thewheel with respect to the shaft 49. j vided with a tire 57 of leather,rubber or other materialhaving the necessary coefficient of friction,and this tire of the wheel 55 cotiperates with a driving disk 58, theaxial adjustment of the wheel 55 with respect to disk 58 enabling theratio of transmission and consequently the relative speed of the wheel55 to be varied. The disk 58 is mounted in the side frame antifrictionbearing 59, which is fixed to turn with the disk 58, and the disk isgrooved to receive a belt 61 which is driven by a pulley 62 on the shaftof an electric or other motor 63,

'Axial shifting of the wheel 55 is accom- 65, this slide haying agrooved lug 64 which cooperates with the wheel'55, and as the slide 6%is shifted longitudinally of the guides 65, the wheelwill be adjustedaxially of the shaft 459. Shifting of the slide 64: is iaccom plished inthe present instance by a pin 66 which is fixed to the slide andoperates in a slot 6'? formed in one end of the adjusting lever -58, thelatter being pivoted on the side frame of. he machine at 69, and havingadapted to 006perate with difier'ent portions of a toothed sector 71whichis fixed to the machine frame for the rocking of the adjustinglever 68, obviously shifting the wheel 55 with re spect to the axisofrotation of the disk 58,

tion of the light throughout the extentof during the printing thesensitized surface operation, so constructed that it may. be readilymoved into operative and inoperative position, the exposing mechanism.while in inoperative position rendering the arc lamps or illumi= hatingmedium conveniently accessible and thereby enabling the other parts ofthe ex-- posing mechanism to be reached and cleaned.

49 and the driving rollers this exposing meoha-' The wheel 55'iswpreferably prothe center or axis of rotation of the 2 of the machineby an too i and this exposing mechanism is its nism comprises a frame 72which is preferably composed of channeled iron, to afford These lampsare mounted on a carriage.

which embodies a part 77 which is contained within the frame 72 and issupported thereon by a suitable number 'of rollers 78. The rollers 78operate longitudinally on the upper sides of the-roller-guides 73 and 74of the frame 72 to permit the carriage 77' and the arc lamps thereon tobe shifted longitudinally of the frame 72 and longitudinally of thecurved glass 23. In the present instance, the carbons or electrodes ofthe arc lamps are inclosed within glass globes 80,

v and these globes are suspended from the carriage 77 by springs orhangers 81 in such a way that the globescan be removed for the cleaningof the lamps and the renewal or adjustment of the electrodes. During theprinting operation the carriage and the lamps thereon are shifted to andfro on the frame 7 2, preferably through a distance equal to thedistance between two adjacent lamps,'for the purpose of distributing thelight uniformly and thereby insuring a uniform tone or exposure to theprints. Difi'erent mechanisms may be employed for shift-- ing thecarriage to produce this result. In the present instance, a pair ofsprings 82 are provided, the outer ends of which are attached to one endof the frame 72, and the inner ends of the springs are attached to thereciprocatory carriage 77, and a cord or chain 83 is detachablyconnected to the opposite end of the reciprocatog'y carriage 77, thiscord or chain passing over an idler roller 84 and'being connected to theslide 85, the latter reciprocating in the stationary guides 86, and theslide is connected to a pitman 87, the pjtman being operated by a crank88 which is fixed to'the shaft 37 of the driving roller 25. As thedriving roller 25 revolves, reciprocatory motion will be iniparted tothe slide 85, and this reciproca tory motion of the slide will betransmitted by the cord or chain 83'to the carriage 77, therebytransmitting a to and fro motion to The exposing mechanism, whichembodies the reciprocatory carriage and its carrier frame 72, is held inoperative position by thumb screw 89, and is held in inoperativeposition by a similar set screw 90, Fig. 1 showing the exposingmechanism in inoperative position and Figs. 4 and 5 showing thismechanism inoperative position. The carriage 77 is preferably coveredand protected by a hood, composed of convergently arranged members 91and 92 which are rigidly connected at the top by a cross member 93 whichis preferably of channel form, to insure the necessary rigidity. Thewinding roller 94 ismounted in fixed bearings above the driving roller25,

this winding roller having a slot 94 adapted to receive the inner end ofthe web before the beginning of the winding operation, and the windingroller is operated from the driving roller 25 by a friction drive whichwill compensate for the increasing diameter of the roll of materialthereon, as the winding operation proceeds, thereby enabling the windingroller- 94 to operate without interfering with the feeding of the. webat uniform speed by the driving rollers 25 and 26.

In the present instance, the rollers 25 and 94 are provided with groovedpulleys 92 and 93 respectively, which are connected by a frictiondriving belt 94, this belt sliding upon the pulleys when the webaccumulates upon the winding roller. The winding roller is adapted towind over the printed web in the form of a continuous or uncut strip.However, in some cases it is desirable to feed the web from the machinewithout winding it upon the roller 94. For this purpose a table'is of astationary section 95 and an adjustable section 96, which is hinged tothe stationary section 95 at 97. The adjustable section 96 of the tablemaybe set in upright position and held in such position by a thumb screw98, as shown in Fig. 1,- at which time it 00-. operates with thestationary" section 95 to form a receptacle to receive the web; or theprovided which is composed adjusting section may be placed in a positionthe web while resting in the slotted plate,

for the purpose of severing the web. An adjustable gage 100 isalsoattached to the outer end of the adjustable table section 96, and bysetting this gage properly,'the web may be cut in lengths or sections ofany desired size.

The roll of prepared paper is mounted on the shaft 128, each end of thisshaft being supported by. a bracket 129 which is fixed to the upperportion of the machine, the rear ends of this bracket being formed withnotches 180 to receive a suitable number of cross ribs 131 which mayserve to suspend the washed prints before eflecting the drying thereof.The paper upon the roller of .the shaft 128 may then be passed throughoperates with the driving pulley 137 of the shaft of the motor 63.

The negatives from which the prints are .to be made are introducedbetween the sensi-v tized material and the glass guide or support, andthe negatives and the sensitized material are fed in unison beneath theglass the traveling belts, and during support by exposure and thisoperation, the necessary printing is accomplished,
